New organic thin-film PV cells used to create power-generating window
Ito Electronic Co Ltd is developing a window equipped with solar cells.
The window, “Smart Power Generation Window,” comes with a wooden frame and can generate 3Wh of electricity per window (44.9 x 101.5cm) per day on average.
The window is made by placing 96 organic thin-film solar cells (polymer type, 5 x 5cm each) between transparent acrylic plates. Specifically, 32 of them have a sunlight transmittance of 0% while the remaining 64 have a sunlight transmittance of 30.4% The conversion efficiencies of the former and the latter are 3.50% and 2.00%, respectively. The rated output per window is 1.2W.
